    Stepan Polyester Polyols for Rigid

    Polyisocyanurate (PIR) and Polyurethane (PUR Foam)

    Increasing energy efficiency through improved insulation


    Stepan is the global leader in the production and sale of aromatic polyester polyols for use in
    rigid polyisocyanurate and polyurethane foams. The largest end use for Stepan rigid aromatic
    polyester polyols is in applications where insulation, flammability, and structural performance
    are most important. These polyols contain innovative Stepan technology that improves foam
    processing and insulating performance to create value in end use applications. Stepan’s
    aromatic polyester polyol business uses a vertical integration model, world-class
    manufacturing and a global supply chain to deliver quality and reliability.
